There are various drugs used to prevent further progression of the disease. In India, there are few studies in relation to treatment outcome in a tertiary care hospital. Aim: To study the treatment outcome of drug therapies used in heart failure patients with associated co-morbidities in a tertiary care hospital. Materials and Methods: This was an observational study conducted on 250 patients with heart failure. Details collected using the proforma were demography (age, gender); medical history; medication history for heart failure patients on admission and discharge; ejection fraction; median length of stay in hospital; number of readmissions & in-hospital mortality. Results: One hundred and twenty eight patients categorized into LVSD group (ejection fraction <40%) and 122 patients in PSF group (ejection fraction > 40%). Medical history of coronary artery disease (54%) was significantly higher in LVSD group (p <0.05) and anaemia (19%) was significantly higher in PSF group (p <0.05). On admission, inotropes (30%), digoxin (59%) and statins (54%) were prescribed more in LVSD patients (p <0.05) while calcium channel blockers (20%) were prescribed more in PSF group (p <0.05). At discharge, patients with LVSD were receiving ACE inhibitors (51%), beta blockers (30%), digoxin (67%) and statins (59%) (p <0.05) while calcium channel blockers (20%) was prescribed more in PSF group. The median length of stay was slightly higher in patients with PSF (7 days) as compared to LVSD (6 days). In-hospital mortality was lower in patients with PSF (6%) than patients with LVSD (20%). The percentage of readmissions within one month was slightly higher in patients with PSF (15%) compared to LVSD (14%). Conclusion: Length of stay in hospital was 6-7 days in heart failure patients. In hospital mortality in LVSD patients (20%) was higher compared to PSF patients (6%). A 15% heart failure patient were readmitted within 1month of discharge.
